enlargements of said slots 19, allow for the passage of the hooks 29 of the spreader until the cuts 30 reach the webslS of the vertical. At this time the cuts 30 may be I slid along the webs 18 until the webs 26 engage the ends of the slots 19, as shown in Fig. 1a, and thus lock the elements together.

A convenient tie 50 (illustrated in Figures 7 and 8) for use with the elements, has each longitudinal edge turned over upon the same side to form longitudinal hooks 51, but if desired, atie with its longitudinal edges turned over upon opposite sides to form longitudinal hooks, maybe used. From Figs. 9 and 10 it will. be seen that the tie members are adapted to be inserted through the slots 27 of the horizontals 1 In. the preferred construction" of the spreader 23 the narrow web has the longitu" .dinal hook 29 formed thereon, thoughthis is not essential, and said web mayhave along its length a plurality of, distanced slots 27 with or without. tongues 28" thereat, said tongues be ng formed as before stated.

Transverse slits or saw cuts 30 are made 111 'said narrow web at the'desired distances I along its length and through aboutone third its width, said slits being through the longitu din'al hook or catch 29 when same is formed on the web. 1

' These slits are entered by the edges of the webs 18 which form a portion of the boundary of the slots in the verticals, and when.

the spreaders have. been threaded through said slots 19 and moved sidewardly'to one end thereof, the verticals and spreaders are interlocked. Y

r A reenforcing frame may be made up of verticals -15 placed at suitable distances apart, and firmly connected together by means of the spreaders 23, and, 1f desired,

the metal slats or stiffeners 50 (preferably with turned over edges 51), may be threaded through slots 27 in said spreaders between theverticals,

The slabs (not shown) are cast or mould.

, ed in moulds of any suitable size, about the is supplied with a layer of material, the reenforcing frame (made up of verticals 15 and spreaders 23 and, if desired", withslats SOthreaded through the latter as stifi'eners) with the narrow webs of the verticals down wardsis laid upon such layer, the hook edge 22 of the wide webs 18 being upwards above up to the required thickness with compo and ]ing from one face of the slab.

the top of the mould, and .asmal] space about one quarter of an inch belng left between the ends of the elements and the sides and ends of the mould, which isthcnfilled faced off, the reenforcing frame thus being embedded but with the hook edges 22 of the verticals protruding clear of one face of the slab.

In another method of casting a slab, the

reenforcing frame with the hook edges 22 of 1 the parallel verticals downwards'has fillers (say of wood) fitted neatly between said parallel verticals and uponand covering the then upturned hook edges'thereof, and is then placed in the mould with said hook edges of the verticals downwards and rest ing upon the bottomof the mould, which. is

then filled up with" compo and faced off, the reenforcing frame thus being embedded but with the hook edges of the verticals protrud- A reenforoing frame of assembled ele- :ments, (preferably, spreade'rs vertically disposed with stiifening'slats threaded llOliZO'i'f: t0 tally through their slots) may. if desired,

be applied to sheets of cement, fibrous plaster, or gypsum, now used in building construction, in order to provide an expeditious, inexpensive and effective reenforcmg of such sheets and means for fastening them on am;

To apply the frame, the prepared sheet of such material is placed on a table or level surface, the upper faceis thoroughlymois 1.00

f tened with-water, the frame with wide webs downwards is placed upon said sheet in alignment with the edges thereof, and with the ends of the stiffeners projectingbeyond those edges (which will be the vertical edges .of the sheet) sufiiciently to enable the said ends to give a good seating on timber studd ng.

The frame isthen' covered with compo,

preferably of a kindred. substance to. the

sheet or of cement mortar, and same is allowed to dry and season, when the reenforced sheet is ready for use. p I

In the construction of buildings with cavity walls, parallel rows of slabs are posi tioned vertically in tiers, apart from one auother the distance of the required cavity, and. with their protruding hooks orv catches facing one'another, (that is inwardly of the wall), slabsof requisite height and length 12o being used to provide openings for windows and doors where desired. The slabs are then tied together by means of ties, made from sheet metal. to the desired width and length,

and with a longitudinal hook along each is erected',"or upon completion"ofi zl e wall to '130 Y the required height. Studs are cast or moulded around the ties the whole height of the cavity wall by placing amould board or wedge upon each side of the ties within the cavity and then fillingthe vertical mould so formed, with selected material.

Piles, posts, beams, sleepers and the like, may be moulded around a frame of assembled elements having slots near each end, and, if desired, at intermediate points, the verticals being disposed longitudinally and arranged to the sectional formation desired, (say circular, rectangular, etcetera), a spreader or plurality of spreader-s being threaded through and locked in said slots.

In lengthy construction, lengths of verticals are overlapped, and a spreader or plurality of spreaders threaded through and locked in the coincident slots in said overlapped ends, and at other points as desired.

I claim 1. An interlocking, reenforcing and fastening element, or vertical for moulded concrete slabs and the like, havin a narrow web with a longitudinal corrugatlon therein and a flat edge portion, and a wide web arranged at right angles to the narrow web and provided with slots therethrough having enlarged p0rtions,'and a longitudinal hook ar ranged at the free edge of said wide web.

An element as claimed in claim 1 having tongues extending from one edge of said slots and arranged in the same plane as the flat edge portion of the narrow web.

3. An interlocking and reenforcing element, or spreader for moulded concrete slabs or the like having a wide web with a longitudinal corrugation therein and a flat edge portion, and a narrow web arranged at right angles to the wide Web and having spaced slits arranged at its free edge.

4. An element as claimed in claim 3 in which the narrow web is provided with spaced slots adapted to receive stiffening elements.

5. An element as claimed in claim 3 in which the narrow Web is provided with a series of spaced slots, and tongues extending outwardly from the slotted portions of said 6. An element as claimed in. claim. 3 in' which the free edge of the narrow web is provided with a longitudinally extending hook through which the slits extend.

7. In a reenforcing frame for molded concrete slabs and the like, a vertical. element having a narrow web with a longitudinal corrugation therein and a fiat edge portion, said vertical element having a wide web arranged at right angles to the narrow web and provided with spaced slots having enlarged portions, he free edge of said vertical element being provided with a longitudinally extending hook, and a horizontally extending element cooperating with the vertical element and including a wide web with a longitudinal corrugation therein and. a flat edge portion, said horizontal element also having a nar ow Web arranged at right angles to the wide Web and provided with spaced slits at its free edge, said horizontal element being threaded through one of the slots in the vertical element, and one of the slits in the horizontal element engaging a portion of the wide web of the vertical element for locking said elements together.

8. In a reenforcing 7 frame for moulded concrete and the like, a vertical element having alongitudinal corrugation and a longitudinally extending hook, said vertical element being also provided with a slot, and a horizontal element threaded through the slot of the vertical element and interlocking with the slotted portion of the vertical element.

9. In a reenforcing frame, a horizontal element having a longitudinally extendingcorrugation an da flat edge portion, a narrow web arranged at right anglesto the flatedge portion and terminating in a longitudinally extending hook, a slot provided in the narrow web, and a stiffening element extending through said slot and bearing upon the flat edge portion of said horizontal element.
